Answer:
New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. ... Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.
